"Suspect in theft of property from Ricky Best has been apprehended,” the department tweeted. “Great job Portland!"

Police released surveillance photos of a man with long hair and a baseball cap fleeing the scene of the attack late Thursday. They said the department received numerous tips from the community of a person matching Tschaggeny’s description who frequented an area near the I-84 highway. The tips led to his arrest.
